The Southwest Monsoon (Habagat) continues to affect large portions of the Philippines on Tuesday, July 7, 2025, bringing scattered rains and thunderstorms, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
PAGASA reported that the Ilocos Region will experience occasional rains throughout the day due to the intensified monsoon activity. Cloudy skies with scattered rainshowers and thunderstorms are also expected in Metro Manila, Cagayan Valley, the Cordillera Administrative Region, Central Luzon, Calabarzon, Mimaropa, Western Visayas, Negros Island, the Zamboanga Peninsula, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).
Other parts of the country may see partly cloudy to cloudy skies, with isolated rain showers or thunderstorms, particularly in the afternoon or evening hours.
Moderate to strong winds, along with mild to rough sea conditions, are forecast along the seaboards of extreme Northern Luzon and the western portions of Central and Northern Luzon. Mariners are advised to exercise caution, especially those operating small sea vessels.
Heavy Rainfall and Flooding Outlook
PAGASA highlighted areas at higher risk for heavy rains, particularly Ilocos Norte and Ilocos Sur, where rainfall may range between 50 to 100 millimeters today. Rainfall totals could be even higher in mountainous and elevated areas, potentially leading to flash floods or landslides. The impacts of today’s rains may also be compounded by prior rainfall in the past days.
Disaster risk reduction and management offices (DRRMOs) and the general public are urged to remain vigilant. PAGASA may issue Heavy Rainfall Warnings or Thunderstorm Advisories to provide real-time updates.
As of 6:00 PM today, PAGASA has released General Flood Advisories (GFA) for several regions:
- CAR (GFA #5)
- Ilocos Region (GFA #23)
- Cagayan Valley (GFA #5)
- Central Luzon (GFA #7)
- Zamboanga Peninsula (GFA #3)
- BARMM (GFA #4)
Advisory Clarification
PAGASA also clarified the difference between Heavy Rainfall Warnings and Weather Advisories. A Heavy Rainfall Warning is a short-term, localized warning that utilizes Doppler radar for real-time accuracy. In contrast, a Weather Advisory offers a broader outlook over 24 hours but only at the provincial level.
